Phone company sent me a bill after I closed my account for a petty amount. So I paid it.

So I recently switched phone service providers. Besides a bit of a headache with migrating my phone number to the new service, things weren't bad. Due to the migration taking a couple days past the end of my normal billing period the previous Provider sent me a bill for let us say $3.50. Postage alone in my opinion made this a bad move on the service provider part but hey, it is a bill so I will pay it.

I don't want to send my money back by mail as that could risk bill never being paid and I don't feel like calling them and paying them over the phone, so I hop on their website and go to their guest pay since my old account was closed when they migrated my account. Turns out guest payments are a $5.00 Min. You would think this is where they are trying to screw me but this is actually why I came to pay online. Due to the bill being under $5 this means they have to send me my change back in the mail. The postage cost of 2 pieces of mail is nearing the difference in change that I expected them to send me.

Their change return mail finally got to me today. They sent me $9 on a debit card. I have no idea how that math works but they are the ones that sent me the bill.
